GAAP net sales for the fiscal year ended March 31, 2017 were $3.408 billion, anincrease of 56.8% from net sales of $2.173 billion in the prior fiscal year. On a GAAP basis, consolidated net income from continuing operations for the fiscal year ended March 31, 2017 was $170.6 million, or 73 cents per diluted share, adecrease of 47.4% from net income of $324.1 million, or $1.49 per diluted share in the prior fiscal year.

Non-GAAP net sales for the fiscal year ended March 31, 2017 were $3.502 billion, anincrease of 58.2% from net sales of $2.214 billion in the prior fiscal year. On a non-GAAP basis, net income from continuing operations for the fiscal year ended March 31, 2017 was $937.1 million, or $3.99 per diluted share, anincrease of 60.6% from net income of $583.3 million, or $2.68 per diluted share, in the prior fiscal year.

Microchip announced today that its Board of Directors has declared a quarterly cash dividend on its common stock of 36.15 cents per share. The quarterly dividend is payable on June 6, 2017 to stockholders of record on May 23, 2017.

"Our March quarter financial results were outstanding," said Steve Sanghi, Chief Executive Officer. "Our net sales were near the high end of our updated guidance from February 28, 2017, while non-GAAP gross margin percentage, operating profit percentage and diluted earnings per share all exceeded the high end of our guidance. We were not able to provide GAAP guidance for the March quarter due to our February 2017 convertible debt offering and the related GAAP accounting impact not being available at that time."

Mr. Sanghi added, “Non-GAAP earnings per share was an all-time record and was 10 cents per share better than the mid-point of our February 28, 2017 guidance, and up 64.7% from the March quarter of a year ago due to improving sales, gross margin percentage, operating expense leverage and the successful execution of our core business as well as accretion from our acquisitions. GAAP earnings per share for the March quarter was heavily impacted by acquisition-related expenses and hence, not meaningfully comparable to the March quarter a year ago.”

"Microcontroller revenue was a record $580.5 million in the March quarter and represented 64.3% of Microchip's overall revenue," said Ganesh Moorthy, President and Chief Operating Officer. "In March 2017, Gartner Dataquest released their microcontroller market share report for 2016 which showed Microchip had gained market share in each of the 8-bit, 16-bit and 32-bit product lines, and climbed to the number three overall microcontroller ranking in the industry by revenue. We believe we have the new product momentum and customer engagement to continue to gain even more share, as we further build the best performing microcontroller franchise in the industry."

Mr. Moorthy added, "Our analog business was also at record levels of $230.5 million in the March quarter and represented 25.5% of Microchip's overall revenue. We continue to develop and introduce a wide range of innovative and proprietary new linear, mixed-signal, power, interface, timing and security products to fuel the future growth of our analog business."

Eric Bjornholt, Microchip's Chief Financial Officer, said, "The cash flow from operations in the December quarter was a record $322.6 million. As of March 31, 2017, the consolidated cash and total investment position on our balance sheet was $1.41 billion."

Mr. Sanghi added, "I want to thank all of the employees of Microchip, including employees who joined us from our acquisitions worldwide for delivering such a strong quarter, as well as an outstanding fiscal year 2017."

Commenting on the business environment, Mr. Sanghi added, "We are seeing a very strong business environment for our products worldwide. Our bookings rate is extremely strong. Our inventories at Microchip as well as at distributors are at the low end of the normal range. Therefore, we are starting to see some lengthening of our lead times. We are starting to see challenges in fab, foundry, probe, assembly, and test capacity. We have increased wafer starts in our three internal fabs and we are adding capacity in our three assembly and test facilities. Despite all this, we are seeing significant business that we are not able to support by the customer requested dates."

Mr. Sanghi concluded, "We expect total net sales to be between $920.7 million and $965.9 million in the June 2017 quarter. Having achieved non-GAAP operating profit of 35.6% in the March quarter which is very close to our long-term target of 36% non-GAAP operating profit, and reflecting confidence in our planned business improvements, we are revising our long-term operating model. Our long-term non-GAAP operating model used to be 60% gross margin, 24% operating expenses and 36% operating profit. Today we are revising it upwards to 62.5% non-GAAP gross margin, 22.5% non-GAAP operating expenses and 40% non-GAAP operating profit. Microchip does not utilize a GAAP long-term operating model.”

¹    See the "Use of Non-GAAP Financial Measures" section of this release.

²    See Footnote 2 under the "Use of Non-GAAP Financial Measures" section of this release.

³    Earnings per share has been calculated based on the diluted shares outstanding of Microchip on a consolidated basis.

• Microchip's inventory days at June 30, 2017 are expected to be 98 to 107 days. Our actual inventory level will depend on the inventory that our distributors decide to hold to support their customers, overall demand for our products and our production levels.

• Capital expenditures for the quarter ending June 30, 2017 are expected to be approximately $60 million. Capital expenditures for all of fiscal year 2018 are expected to be approximately $170 million. We are continuing to invest in the equipment needed to support the growth of our production capabilities for fast growing new products and technologies.

¹  Use of Non-GAAP Financial Measures: Our non-GAAP adjustments, where applicable, include the effect of discontinued operations, share-based compensation, expenses related to our acquisition activities (including intangible asset amortization, inventory valuation costs, severance costs, and legal and other general and administrative expenses associated with acquisitions), preclusion of revenue recognition under GAAP for inventory in the distribution channel on the acquisition dates of our acquisitions, revenue recognition changes related to Atmel and Micrel distributors resulting from changes to business practices with those distributors, a loss

on the inducement and extinguishment of our convertible debentures, non-cash interest expense on our convertible debentures, gains on equity securities, impairments on available-for-sale investments, the related income tax implications of these items, tax adjustments in accordance with ASC 740-270 and non-recurring tax events. Our non-GAAP results for the twelve months ended March 31, 2017 reflect an adjustment for a manufacturing excursion issue with one of our suppliers. Our non-GAAP net sales outlook for the June 2017 quarter reflects accounting for revenue for Atmel distributors on a sell-through basis. Net sales from Atmel's sell-through distributors that the distributors owned as of the acquisition date is not recognized for GAAP purposes. We believe that our disclosure of non-GAAP net sales provides investors with useful information regarding the actual end market demand for our products.

We are required to estimate the cost of certain forms of share-based compensation, including employee stock options, restricted stock units and our employee stock purchase plan, and to record a commensurate expense in our income statement. Share-based compensation expense is a non-cash expense that varies in amount from period to period and is affected by the price of our stock at the date of grant. The price of our stock is affected by market forces that are difficult to predict and are not within the control of management. Our other non-GAAP adjustments are either non-cash expenses, unusual or infrequent items or other expenses related to transactions. Management excludes all of these items from its internal operating forecasts and models.

We are using non-GAAP net sales, non-GAAP gross profit, non-GAAP gross profit percentage, non-GAAP operating expenses in dollars and as a percentage of sales including non-GAAP research and development expenses and non-GAAP selling, general and administrative expenses, non-GAAP operating income, non-GAAP other expense, net, non-GAAP income tax rate, non-GAAP net income from continuing operations, and non-GAAP diluted earnings per share from continuing operations which exclude the items noted above, as applicable, to permit additional analysis of our performance.

Management believes these non-GAAP measures are useful to investors because they enhance the understanding of our historical financial performance and comparability between periods. Many of our investors have requested that we disclose this non-GAAP information because they believe it is useful in understanding our performance as it excludes non-cash and other charges that many investors feel may obscure our underlying operating results. Management uses these non-GAAP measures to manage and assess the profitability of our business. Specifically, we do not consider such items when developing and monitoring our budgets and spending. Our determination of the above non-GAAP measures might not be the same as similarly titled measures used by other companies, and it should not be construed as a substitute for amounts determined in accordance with GAAP. There are limitations associated with using non-GAAP measures, including that they exclude financial information that some may consider important in evaluating our performance. Management compensates for this by presenting information on both a GAAP and non-GAAP basis for investors and providing reconciliations of the GAAP and non-GAAP results.

²  Generally, gross margin fluctuates over time, driven primarily by the mix of microcontrollers, mixed-signal products, analog products and memory products sold and licensing revenue; variances in manufacturing yields; fixed cost absorption; wafer fab loading levels; costs of wafers from foundries; inventory reserves; pricing pressures in our non-proprietary product lines; and competitive and economic conditions. Operating expenses fluctuate over time, primarily due to net sales and profit levels.

³  Diluted Common Shares Outstanding can vary for, among other things, the trading price of our common stock, the exercise of options or vesting of restricted stock units, the potential for incremental dilutive shares from our convertible debentures (additional information regarding our share count is available in the investor relations section of our website under the heading "Supplemental Financial Information"), and repurchases or issuances of shares of our common stock. The diluted common shares outstanding presented in the guidance table above assumes an average Microchip stock price in the June 2017 quarter between $77 and $80 per share (however, we make no prediction as to what our actual share price will be for such period or any other period and we cannot estimate what our stock option exercise activity will be during the quarter).
